CAR-COUPLING.

' To all whom it may concern:

tion showing the connection between the coupler head and the\shank-.

'My invention relates to automatic couplers of the Master Car Builderstype, and is designed to provide means for angling the coupler-headrelatively to its shank in a vertical direction, so that when coupledwith a -.co-acting coupler there is provided a Verti '20 flexibility ofthe two couplers, which permits the coupler-heads to adjust themselvesto the irregularities in and changes in grade of the tIaCk .WlthO11i3injury.

Referring to the drawings, the numeral 2 designates the coupler-headhaving a rearextension 3 are two outside projections 4 and 5, and acentral projection 6, all of which projections have registeringapertures for the insertion of a hbrizontally disposed pivot pin 7. Atthe forward end of the hollow coupler shank 8 are lugs 9 and 10, whichen: ter between the projections 4 and 5 of the coupler-head 2 and takeabout the central projection 6.0f the coupler-head 2. These lugs 9 and10 also have registering apertures for the reception of the pivot pin.The central projection 6 projects 'rearwardly of the bear; against theinside surface 15 pivot pin and has made integral therewith the springseats 11 and 12 upon which the springs 13 and 14 are positloned, andwhich of the coupler shank. These springs are of sufficient strength, byreason oftheir bearing on the extension 6, to hold the coupler-headnormally in horizontal central alinement with the coupler shank 8, thelower spring 14 Specification of Letters latent.

yieldingly resisting the downward move ment of the coupler-head. The.alinement of the co-acting couplerheads is preserved by reason of thevertical flat outer face 16 of the knuckle which engages thecorresponding face of the opposing coupler when coupled therewith andunder buffing stress. t

The location of the horizontal pivot pin 7 is as close to thecoupler-head as is practi- Leable, and as it lies substantially at theuncture between the head and the shank of an ordinary coupler, itpermits the greatest possible amount of angling resultant upon any givenamount of movement of the coupler head.

The present day construction of cars and the position of the couplerthereon, as well as the small clearance provided in the contour line ofthe coupler, makes it impossible to allow for other than a very smallchange of angle in a vertical direction between the cars withoutdamaging the coupler. Hence, the value of my device is obvious, sincefrom the advanced position of the horizontal pivot, which I havedescribed, a slight movement of the parts will admit of a relativelygreat change of vertical angle between the shanks of co-acting couplers.

What I claim is:

1. In a car coupling'mechanism of the Master Car Builders type, acoupler-head having vertically disposed projections extending rearwardlytherefrom, a hollow coupler shank having vertically disposed forwardlyextending lugs, a horizontal pivot pin, said lugs and projections havingregistering apertures for the admission of the pin, one of saidprojections having at its rear end spring sea-ts, springs mounted onsaid seats and bearing against the interior of the coupler shank, andbeing adapted to hold the coupler head normally in horizontal alinementwith the coupler shank,

2. In a-car coupling mechanism of the cally extending lugs, saidprojections and lugs having registering apertures for the admission of apivot pin, a central extension projecting rearwardly from the couplershank to the rear of the pivot pin and being adapted to be positioned inthe shank of the coupler, and to co-aot Withmeans for nor- J I I maliymaintaining the coupler head in horizontal ahnement with the couplershank.
